Heat Pump Model: 2TWR1030A1000B
Does anybody know the metering devices used for this heat pump?
Their location would be helpful as well.
Whilst replacing the evap coil, we found that the old unit had NO
orifice. The instructions for the new one called for an orifice.
How could the old one have worked? It was maybe eight years
Do they have some kind of bi-flow out at the heat pump?
Double-metering wouldn't be good.
